GUN.

Application filed .Tune 29, 1916, Serial No. 106,675. Renewed November22, 1922.

To @ZZ whom t may concern Be it known that I, JOHN LUND, a citizen ofthe United States, residing at Bethlehem, Northampton County, State ofPennsylvania, have invented certain new and usei'ul Improvements inGuns, of which the tollowing is a specification.

This invention relatesto guns and more particularly to guns andcarriages which are separable into convenient parts, for transportation.u

The main object of the invention is to provide a gun so constructed thatit may be quickly and easily knocked-down or set-up without in any wayseparating the delicate moving parts such as the recoil mechanism,elevating mechanism and traversing mechanism. i

These and other features of the invention will be described inconnection with the drawings and pointed out in the appended claims. i

In the drawings, in which like reference characters indicate the samepart,

Figure l is a side elevation of the gun and carriage, certain partsbeing broken away to show other and hidden parts in section;

Figure2 is a side elevation of the gun bari rel and sleigh forsupporting the same, the latter appearing in section;

Figure 3 is an end elevation of the parts shown in Figure 2 as seen fromthe right;

Figure 5 is a sectionall view on the line 5-.5 of Figure 4 showing themanner of connecting the front end of the gun barrel and the sleigh;

Figure 6 is an end elevation of the cradle and part of the elevatingmechanism;

` Figure 7 is a side elevation of the cradle and part of the elevatingmechanism;

Figure 8 lis a sectional view taken ou either of the lines 8 8 of Figure7 Figure 9 is a side elevation of the top carriage, the axle and platelocked to the saine being shown in section;

s Figure l0 is a front elevation of the axle and plate, showingthejmanner of locking the latter to the axle.

Mountainy guns `are generally knocked down for transportation, byseparating the l.parts of the gun whichk move relative to each other infiring or adjusting the gun. Thus,

in removing the gun barrel, the guides on Figure 4 is an elevation ofthe opposite Again in rel with the consequent injury to the gun, by

providing means whereby the gun maybe dismantled or knocked-downwithoutseparating any of the parts which move on each other when tiringor adjusting theugun.

As shown inv F iguresl and2, the gun barrel 2O is adapted'to be attachedto a sleigh 2l. This sleigh reciprocates on guides '3l provided on thecradle. The gun barrel is connected to the sleigh 21 by means at thefront and rear ends thereof.y At thelfront end the gun barrel isprovided with two prongs 22, which are adapted to iitin correspondingrecesses 23 formed near the end of the sleigh. While two prongs areshown, v

it is obvious that a greater' or less number' might be used. y At thebreech end of the gun a.. downwardly extending lug 24 is providedL whichis adapted to extend into a hollow or recess 25 formed in thecorresponding end ot the sleigh. As shown, the rear face of the lug 24is substantially perpendicular to the axis of the barrel. The oppositeface,

however, is inclined so that the lug has the form of a wedge. Thestraight side ofthe lug is adapted to contact witha correspondingstraight surface in the recess 25 and the inclined side of the lugcooperates with a similarly inclined surface in the `recess 25 so thatwhen the lug is introduced into the recess it will tit tightly thereinbecause of the inclined side. The sleigh is formed with a substantiallysemi-cylindrical seat 26 and the lug 24 is provided with a correspondingseat 27 which is adapted to register with thc 'first seat, the two seatswhen in register forming a complete cylindrical surface. A pin28 isrotatively mounted andv adapted to nt in they seat 26 andvis providedwith a handle 29 whereby it maybe rotated. At the oppositev end from thehandle it is threaded and a nut 69 fitted thereon vso that the pin maybeheld in proper position. On one side for a distance substantiallykequal to the breadth of the lug 24 the pin is ioov slabbedofto providea flat surface 29. The arrangement ot this flat surface is such thatwhen the pin is rotated` to proper posi the said surface will lie yflushwith .the ccntacting surfaces ot the lug 24 and recess 25. thuspermitting` the lug to be withdrawn troni the recess 25. it willtherefore be apparent that it vthe pin 28 is turned to the abovementioned `position that the `lug 24 may be withdrawn from the recessand thereafter the prongs 22 inay be disengaged trom the recesses 23 bymoving the barrel ot theV gun slightly in a forward direction. rlhus thegun barrel will be disconnected from the sleigh 2l and withoutdisturbing any parts which move on each other while the gun being tired.The sleigh 2l provided at' opposite sides with ways 3U- which areadapted to slide on vthe guides 3l carried by 'the cradle. iis shown inFigure i., the end of the sleigh which has the recess 25 formed thereinis connected to the recoil mechanism 32,-the latter being carried in acylinder 33.

rlhe structurewhereby the cradle may be separated from the top carriagewill now be described. The trunnion plate 34 is riveted to the cradleand 'carries the oppositely e1;- tendingtrunnions 35. which are adaptedto seat inthe trunnion bearings 36 on the top carriage andto be held inplace by hinged caps (not shown). Connectedto the cradle by meanspresently to be' described is an elevating segment 37, which is adaptedto be engaged by'worin 38, the latter` being carried bythe top carriage.Guides 37 on either side ot this elevating segment engage corresponding=grooves Aot the elevating worm bearings 38, preventing these two partsfrom being` separatedexcept by means ot continual turning ot the wormuntil these two members are disengaged. rl`he upper side ot theelevating segment is formed with two upwardly projecting lugs 39 and 40,which are adapted to engage corresponding lugs 4l and 42 formed on thetrnnnion plate. ris clearly shown in Figure 7, one of the faces otthelug 40 and a corresponding tace ot the lug 39 are inclined andadapted to engage correspondingly inclined surfaces on the trunnionplate. The lugs 39, 40, 4l and 42 are ,termed with alined bores 43 inwhich is adapted to seat apin 44. provided with a handle 45. The wallbetween the bore 43 and the bottom ot each of the lugs 41 and 42 is cutaway as at 46 in Figure 8. Adjacent the two lugs 41, 42 the pin 44 hasits opposite sides slabbed o1'i` as at 47 `and 48 so that when the pinis turned with the two slabbed surfaces substantially vertical thetrunnion plate and its connectedcradle may be renioved :tronithesegment, the pin 44 sliding through the openings 46. It is thereforeapparent that the cradle may be separated from the top carriage withoutdisturbing` the 'two plates 50 spaced. end to end which are providedwith lugs 5i. 'forming grooves 52 adapted to lit and Slide on the guides53 provid'efil on a traversing plate 54. Any suitable traversingmechanism is provided and operative between the plates and 54 vwhere- Yby these plates maybe moved longitudinally with respect to eachother. isVshown a worm 'TO carried by plates 50 engages-teeth 54 on the edge ofplate 54. taclied tothe plate 54 and adjacent one end is a pair ofdownwardly extendingprongs 55 and at the other end is another pair otoppositely projecting prongs 5G. The two prongs o the pair 55 andlikewise the pair 56 are each spaced apart so as to straddle the axle57. The axle is formed with two transversely eX- tendingg; bores 58which are located so as to register with the inside curved surfaces ofthe prongs 55and 56. A pin 5,9 is adapted to tit'in each ot the bores 58and is provided with a handle 60 for rotating the same. Adjacent theprongs 55, 56 each ot the pins 59 slabbedotf as shown at 61 in Figure l0so that when the said slabbed off portion is arranged kvertically theend (32 ot' the prongs nia-y pass by the pin so that the plate r54 maybe disconnected troni theaxle. is clearly shown in Figure 9 the pins 59are formed with a groove 63 into which is adapted to project a set screwG4, t'or `the `purposeotl holding` the said pins @longitudinally inposition. A. spring pressed pin`65 maybe provided and adapted to engagerecesses 66 in a pin 59 'to hold the Said pin in'either a. positionwhich locks the plate 54 to the axle or onewhichpermits it to be removedthere from.

In the operation ot the construction which has just been descrilied thegun barrel is removed from the sleigh by turning the pin 28 throughsubstantially G00 'troni its locking position, then raisin-p; thecorresponding end ot the gun barrel, then moving' the` gun barrelslightly Aforward to disengage `the prongs 22 at the 'forward end ot thecradle. The gun barrel is then entirely free of the sleigh. The sleigh`andI cradle which includes the recoil mechanism may now be removed fromthe top carriage by turning the 'pin 44 through ,substantiallyQOO Aandthe additional operation ot opening the hinged trunnion caps previouslyreferred to. The next; step isV to turn the pins 59L each throughsubstann tially 1809. vThe plate 54, together with the assembledtraversing and elevating mechanisin. or in other words the top`carriage, may then be removed from the axle.

It is obvious that a gun construction has been provided which permitsthe knockingdown or disassembling of the same for shipment withoutdisturbing any of the parts which move on each other when the gun isbeing fired or adjusted.
